ADJUSTABLE SELF-CLAIVIPING BRACKET.

SPECIFICATION forming part of Letters Patent No. 766,605, dated August2, 1904.

Application filed ly 1, 1903. Serial No. 163,909. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES H. J. DILG, a citizen of the United Statesof America, and a resident of New York, in the county and State of NewYork, have invented a certain new and useful Adjustable Self-ClampingBracket, of which the following is a specification.

My invention relates to supporting-plates or combination of platesordinarily of moderate projection generally springing from a verticalsurface and in particular to an adjustable metal plate of suitableconfiguration that may be engaged with and locked to and also detachedat will from any support desired in order to serve as a means of holdingarticles; and it has for its object the provision of a device of thekind set forth simple in construction, inexpensive to manufacture, andefficient in practical use.

To attain the desired end, this my invention consists in novel devicesand combinations of devices hereinafter described.

In order to enable my invention to be fully understood, 1 will proceedto explain the same by reference to the drawings, which accompany andform a part of this specification, in which- Figure 1 represents a sideelevation of one of my brackets and support therefor. Fig. 1 is a planview, and Fig. 1 a rear elevation, of the same. Fig. 1" is a view indetail of my locking-joint. Fig. 2 is a side elevation of anotherbracket and support constructed according to my invention. Fig. 2 is aplan view, and Fig. 2 a rear elevation, of the same. Fig. 3 is a sideelevation of another one of my brackets and support. Fig. 3 is a planview of the same, and Fig. 3 a view in detail of the end of the bracketand holding-plates therefor. Fig. 4: is a side elevation of anotherbracket and support constructed according to my invention. Fig. L is aplan view of the same, and Figs. 4" and 4" are respectively views indetail of my locking and clamping devices. Fig. 5 is a side elevation ofanother one of my brackets and support. Fig. 5 is a plan view of thesame. Fig. 6 is a side elevation of another bracket and supportconstructed according to my invention. Fig. 6 is a plan view of thesame; and Fig. 6 a View in detail, partly in section, of my clampingmeans. Fig. 7 is a side elevation, and Fig. 7 a plan view, of anotherone of my brackets and support.

Like letters of reference indicate like parts in all the views.

1 have found it desirable to produce a selfclamping bracket that may beengaged with a support and adjusted to any desired height or inclinationand locked in said position and that may be also detached from the saidsupport at will without disturbing any other brackets attached to thesaid support that may be located above or below the said bracket, and lhave therefore constructed according to my invention a device of theclass described embodying the preferred construction of parts and theirmutual relationship, combination, arrangement, and organization in acomposite body or structure, as hereinafter described.

Referring particularly to the drawings, A denotes a support consisting,in the present instance, of a metal rod.

B and B are my holding-plates, consisting of vertical parts curved attheir rear portions in order to conform to the contour of the rod A andare preferably locked together by means of the engagement of the tongue7) of the plate B with the slot Z) of the plate B. The plates B and Bare provided with similar vertical slots o to form a seat for the pin C,the upper portion of each of which slots is extended forwardly in ahorizontal direction for a short distance in order to form a pocket orseat for the pin U when the same is moved out of the slots if. Thecurved outer or front edges of the plates B and B are preferablyprovided with a series of notches or recesses 7).

My bracket l) preferably consists of a metal plate of suitable form orconfiguration, the rear portion of which is provided with a series ofbearing-surfaces (1, preferably eccentrically disposed as regards theseat of the pin 0 in the slots ZF and intermediate recessed portions (Zand also carries a pin C. The

upper edge or face of my bracket is beveled, as at (Z and my bracket isalso provided with a slot E, in the end of which is fastened a pin F,carrying a movable locking-plate f, and a spring 1, located rearward ofthe same.

After the plates B and B are clasped to the rod A and moved up or down,ifv necessary,

until in the required adjusted position as re-.

eccentrically engaging clamping means, .one

of the bearing-surfaces (Z will rest against the rod A and the pin Cwill be forced to travel into the horizontal extension of the slots 6 Inorder to rigidly lock the parts in the adjusted position after beingthus clamped together, the locking head orplate f, which is normallyheld in the enlargement e of the slot E, may be released from the same,and being carried forward by the resilience of the spring f engages andis held in one of the recesses or notches b It will thus be seen that myadjustable selfclamping bracket may be attachedto and detached from thesupport A without the use of any extraneous parts, inasmuch as theadjustable support-engaging means, the eccentrically-working clampingmeans, and the locking means all form portions of my bracket, consistingin the device under consideration of three mem hers-namely, theholding-plates B and B and the bracket-plate D. In cases Where there area number of brackets held by a support additional brackets constructedaccording to my invention may be added to the support or their numberreduced and their height and inclination varied without disturbing anyof the others.

The rod A of the bracket shown in Fig. Qis clasped by the holding-platesB and B, preferably provided with a dovetailed joint and with slots 6The bracket D has a practically curved face consisting ordinarily of aseries of eccentrically-located bearing-points (Z and a beveled portion,as (Z and also carries apin 0 My locking means consists of a series oforifices (Z formed in the bracket, and an orifice a located in the plateB and constructed and arranged to register with the former at differentinclinations of the bracket. A pin G, carried by a plate g, which workson a post g, supported by theplate B is constructed and arranged toenter one of the orifices (Z and the orifice b when they register witheach other and is held in a locking position by the spring When theparts are not in a locked relation, the edge of the pin G may be raiseda sufficient distance to rest on the plate B In the bracket constructedaccording to my invention and shown in Fig. 3 the holdingplates B and Bare inserted in the channelsupport A, and when the bracket D which isU-shaped in cross-section, is placed in the said support the preferablyeccentric bearing-surfaces (Z work against the rear face of thechannel-support and the outwardly-turned edges 6 and 7)? ofthe plates Band B bear against the inwardly-turned edges (0 of the said support.

The holding-plates B and B and the bracket D (shown in Fig. 4) areloosely held to the support A by means of the screw H and wing-nut H,and after the bracket is positioned by operating theeccentrically-located engaging clamping means the parts are rigidlylocked in position by the engagement with the milled hearing it of thescrew H of the serrated orifices 6 and (Z of the bracket 1) andholding-plates B and B D is provided with a slot cl, the lower part ofwhich is turned rearwardly, and also with a dog J, carrying alocking-pin (Z and a spring (Z gaged with the support is held in avertical position or parallel to the support A, the smaller end of thesame extending upwardly. The locking-pin C 42 is held away from the endof the slot d and the part cl is entered between the two sides of mybracket, the pin The bracket D upon being en-.

a entering the longer portion of the slot (Z which now lies in ahorizontal position. By now pushing the bracket toward the support andturning the same a little the pin a will enter the shorter part of theslot and rest against the end of the same, which forms a seat or hearingfor the pin (0. Then by turning the bracket in a downward direction thepreferably eccentrically located engaging bearing-surface c of thebracketwill engage with the outer face of the channelsupport;

whereby the bracket may be clamped to the support in any one of a numberof desired predetermined positions or at any predetermined inclinationwith respect thereto, the bracket being thus held in a relativelychangeable and detachable relation. After the bracket has been adjustedor moved to any desired height and predetermined inclination or positionthe pin cl may be entered in the slot 6 and engaged with anyone of theseries of recesses a, thus locking the parts rigidly together. Bymanipulating the locking-pin c and moving the bracket upwardly again itmay be readily and quickly disengaged from the support.

The bracket shown in Fig. 6 is provided with a slot 0Z havingrearwardly-extending recesses (Z and carries a bifurcated T-shapedpivoted dog J and a loose eccentrically-disposed dog K, provided with apin Z. working in the slot (Z the two dogs being preferably connected bya spring L. The head or free end of the dog J is rectangular in form andis so constructed and arranged that when held lengthwise with andparallel to the channel-support A the bracket being in a verticalposition, it may be slipped in the slot thereof, after which the bracketmay be turned around so as to assume a horizontal direction, whereuponthe ends of the dog J will bear against the interior of the front wallof the channel-support A and the neck of the same will work in thechannel-slot. The end of the preferably eccentrically-disposed dog K isformed with a central projection or nose is to enter the slot of thechannel and with preferably milled portions 7: to bear against thepreferably milled outer face of the channel-support. After the bracketis positioned the parts may be locked by the engagement of the pin Xwith one of the recesses d and the end of the dog K with thechannel-support and the neck of the dog J. In Fig. 7 the bracket issimilarly formed except that the end of the dog K is curved or formed inhook shape in order to he slipped on and off the supporting-rod A, andthe face of the dog K is made concave in crosssection in order toconform to the curved face of the support.

It is manifest that various omissions of some particulars could be madewithout materially affecting the essential features of my invention orthe operation of the remaining parts, and I do not, therefore, wish tobe limited to the specific structural details of the organization hereinset forth. Obviously the elements of the structure described may belocated at an angle to the plane in which they are shown. I accordinglyuse the words horizontal, vertical, and the like in a relative sense.

In operation a bracket constructed according to my invention may beapplied to a support at any point of the said support in the mannerdescribedthat is to say, it may be inserted between two brackets alreadypositioned in a show case or window and serving to display articles ofwear or other goods without disturbing any of the said brackets orrearranging the said window display, or one of the group of brackets maybe removed without having to manipulate the other brackets. My bracketmay be disengaged from the support by reversing the operation describedof engaging and attaching the bracket to the said support.

Inasmuch as my bracket preferably engages the support eccentrically inorder to clamp the bracket thereto, it may be not only attached to anddetached from the support without disturbing the other brackets by whichit may be surrounded, but it may also be rigidly locked to the supportat any height or at any inclination desired in respect to the saidsupport.

As it is evident that many changes in the construction, form,proportion, and relative arrangement of parts might be resorted towithout departing from the spirit and scope of my invention, I wouldhave it understood that I do not restrict myself to the particularconstruction and arrangement of parts shown and described; but that suchchanges and elquivalents may be substituted therefor, and t 1at What 1claim as my invention is 1. A support, in combination with an adjustableself-clamping bracket provided with means to lock the bracket to thesupport at different heights and inclinations.

2. In combination, a support and a bracket, and means constructed andarranged to engage the support at any point of said support to clamp thebracket thereto and also to rigidly lock the parts together at a numberof predetermined inclinations of the bracket with respect to thesupport, and also to detach the bracket from the support at will.

3. A support, in combination with an adjustable self-clamping bracketprovided with means to engage the support at any point of said supportata number of desired inclinatlOlIiS, and to detach the bracket therefromat w1 4. In combination, a support and a bracket, and means constructedand arranged to engage the support eccentrically to clamp the bracketthereto and to rigidly lock the parts together at a number of desiredinclinations.

5. In combination a support and a bracket, and means constructed andarranged to engage the support eccentrically at any point of saidsupport to clamp the bracket thereto, and to rigidly lock the partstogether at a number of desired inclinations, and to detach the bracketfrom the support at will.

In testimony of the foregoing specification I do hereby sign the same,in the city of New York, county and State of New York, this th day ofMay, .A. I). 1903.
